31. Mechanism of separation by inverse liquid chromatography packed with extraction residue from coal

Abstract

Coals of various rank of coals were extracted with CS_2-N-methyl-2-pyrrolidinone mixed solvent (1:1 by volume) at room temperature. The residues were packed in column using chloroform or n-hexane as a mobile phase solvent. Polystyrene standard samples and various polycyclic aromatic hydrocarbons were injected as a probe to investigate cross-linking structure of coal and interaction between probe molecule and coal.
